Different phases of the classical waterfall model
The classical waterfall model is intuitively the most obvious way to develop software. Though the classical waterfall model is elegant and intuitively obvious, it is not a practical model in the sense that it can not be used in actual software development projects. Thus, this model can be considered to be a theoretical way of developing software. But all other life cycle models are essentially derived from the classical waterfall model.
So, in order to be able to appreciate other life cycle models it is necessary to learn the classical waterfall model.
